This "more stuff deleted" would have been the interesting part; the
kernel will tell you something about the partition table it
recognizes, or at least the device. So if you are sure your device
contains a valid partition table with at least one valid partition,
you should have seen something like:
...
hda: probing with STATUS(0x50) instead of ALTSTATUS(0x41)
hda: CF 128MB, ATA DISK drive
ide0 at 0xc7000320-0xc7000327,0xc3000106 on irq 13
hda: 250368 sectors (128 MB) w/16KiB Cache, CHS=978/8/32
Partition check:
hda: hda1

Yes, most probably.

No, I don't think so.
My guess is that you forgot to enable any partition table support in
your Linux kernel. Make sure your config file contains:
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_BLK_DEV_MPC8xx_IDE=y
CONFIG_BLK_DEV_IDE_MODES=y
and
CONFIG_PARTITION_ADVANCED=y
CONFIG_MAC_PARTITION=y
CONFIG_MSDOS_PARTITION=y
CONFIG_NLS=y
CONFIG_NLS_DEFAULT="y"
CONFIG_NLS_ISO8859_1=y
CONFIG_NLS_ISO8859_15=y
